IMPROVEMENT IN STEAM WATER-ELEVATORS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM L. HORNE; of Batavia, in the county ot'Kane, and State of Illinois, have invented a certain new and usefulImprovementI on Steam Water-Elevators and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation ot' the same, reference being had to the accompanyingdrawings, and to the letters and marks thereon, which said drawings formpart of this specieation,I and byl Figure 1 show, in elevation, awater-elevator, with my improvement as a part thereof, and by Figure 2 aview, by vertical section, ofthe same.

In both of these gures like letters are used to designate like parts.Y

The present invention is of the character of an additionalimprovement-to the invention on which Letters .Patent were granted to meonfthe 28th day' of May, 1857, wherein the water-elevator consists of anexterior -cylinder, a, and an interior valve-cylinder, b, moved, in theone direction by water, and in the other direction by steam. 1

As is shown by fig. 2 ofthe drawings of this specification, to the lowerpart of thc'elevator there is an inletvalve, c, for the admission'of thewater, and at the upper partof th'e elevator a steam-valve, d, forcontrolling the steam-port e of the steam or valve-chestf. Thesteam-valve is atlixed to a rod, g, which passes through a hole in thecap z of valve-cylinder 6, and through another hole in the cross-bar orplate z', attached to the lower end of the cylinder b, so that when thevalve-cylinder 6 is forced downward by the pressure ofthe steam, the barz', acting upon the pin or tappet j, will draw the rod g down, and withit the valve d, closing the steam-port, and as the water elevates thecylinder b-the water coming in on the condensation of the steam-tl1e cap7L of the cylinder will act upon the pin or tappet 7c, carrying up thorod and valve ci,l and opening the steam-port for the admission of thesteam. Fig. 2 of the 'drawings represents the parts in the condition'atthe ond of the stroke of the cylinder on the expulsion of the water. 4

The steam water-elevator, constructed as herein recited, and as setforth in theLetters Patent above referred to, is liable to beinterrupted in Vits regular effective action by air'or gas accumulatingwithin it, and to avoid this is the object of the present invention,which consists in adding to or combining with the outlet or escapeportfor the water, marked m, a siphon-pipe or tube, n; Whatever air or gas'is driven down by the descent of the cylinder 6 tothe port m willreadily pass out through this Siphon n, and whatever air, ges, or steammay lie above the steam-valve d, will pass out through the pipe o intothe siphon,so that the unter-elevator will not labor under the diiicultycaused by air or gas accumulating therein. I

What I claim as my invention, and desire to secure by LettersPatent, is-F The combination of the siphon n with the steam Watenelevator,constrlcted and operated substantially as herein set forth.

This specication signed this 24th day of July, 1867.
